Application and August s, 1913. serial No. 753,791.'

Cleveland, inthe county of Quyahoga'and State of Ohio, have invented a certain new and 'useful AImprovement in Linotype Casting Mechanism, Of which the following is a full, "Cleary and exact description, referthe accompanying drawl g.The object-Of this invention is to provide simple and eective means for making line slugs of short height and grooved on theiropposite sides. Such slugs are very useful in printing machines having railed chases,v in marking machines, in address plates, etc'.

' My invention comprises a mold adapted to bemounted von the mold wheel of a standard Mergenthaler or linotype machine and adapted to vcooperate with the melting pot and matrices for the casting ofa line slug having a base portion and ahead portion which yis grooved on its opposite sides.

After casting, the base portion is broken o'if,

or otherwise severed, leaving the line slug of the form desired.

Theeharacteristics of the invention are Y hereinafter fully explained and are sum-v marized in the claims.

v ing in In the drawings, Figure 1 is a side eleva-` tion of a portion of a mold wheel of a Mergenthaler machine .equipped with my special mold; ,F ig. 2 is a radial section through suchwheel showing a cross section of `the mold; Figs. 3, i and 5. are cross sec'- on the correspondingly numbered lines on Fig. 1.

As shown in the drawing, 1Orepresents the mold wheel of a line casting-machine. My'mold is Carried by 'this wheel and comprises a pair of members 1l for the body of the slug, a pair of members for the head of the slug, and a pair of members 13 for the end of the slug. lThe 4members 117 comprise two bars or blocks seating in an openthe m'old wheel and having their inner faces parallel and'. spaced apart, according to the width of the shank of the slugs. These bars 11 are provided near their ends withears 15, between which'are, carried the tongues 16 of the end blocks 13. The end blocks are rigidly clamped in place by screws 17 screwing through theY ears. This makesz a I rigid rectangllar frame bounding the b'ody of theV is set into'a correspondingly shaped oponmg 1n themold wheel 'and is secured thereto by screws 2O which pass. through side flanges 21 of the block 1l. v

The' members v12which form the mol'dfor the head portion of the slug have peculiarlyformed coperatin faces, namely,y at 'the inner edge of the 'the outer face of the shank portion ofthe mold opening and leading inwardly there.

from; then the face has a groove 25; outside of this groove is a rib 26, and, beyond the rib, a of the 30 (Fig. 2) are against the blocks 12, a'mold rabbet 27 leading to the outer side' block 12. When the lines of matrices.

ace is a bevel 24 joining space is provided corresponding to the slug B there shown. After such slugiis cast v and removed from the mold, it is onl necessary tovremove the portion B from t e head portion' vby breaking-it off, for example, to leave a line slug which is of short height and lgrooved on its opposite sides; that is vto say, a slug corresponding to the portion A inI Fig. 2.

To enable. the' removal ,of the cast slug A, B, I mount the members 12 pivotally on the members 1'1. v12 may have ears 32 which extendy ontoopposite ends of ears 33 formed on the'blocks 11, and hinge pintles 31 pivot the ears together. A spring 35 surrounding the pintle 34 and bearing, as shown, against the blocks To eect .this the members i 12 and against the mold wheel, tends to keep -these blocks in the seated position shown. ln this position beveled ribs 3T on the blocks 12 seat in correspondingly formed grooves in the blocks 11 and accurately position the blocks 12 to hold them against displacement during casting.

After the casting Operation, the mold wheel turns the mold to aposition opposite a suitableV plunger, against the foo't of the cast slug, shoves the whole slug outwardly between thevmovable .members 12, these members swinging on their pivot rods to allow the slug to clear.

them. r1his clearing. actionis made easier by slotti-ng the eyes in the ears 12 about the rod 34, as shown at 39 inFig. 5. grooves 25 may be slightly rounded at one or both inner edges.

and such plunger, acting Aish the In casting, the mold is held` aSJgidaS- if it were a solid' member, point, as soon .as the e]ector beglns to shove outlthe cast slug, the members 12 are freed,

but,1at the ejectionf free fromvthe corresponding grooves in the members l1, and this lets the members l2 I separate slightly (by reason of the slots 89),

5 so that they roll out from the grooves cast in the slug and easily clear it, the'body of the slugs' being vshoved between the swung members into any suitable receptacle.

Having thus described my invention, what .I claim is:
